Hindle testing of the off-axis convex ashpere surface
Hindle testing of the convex aspherical surface is one of the classical methods
which has the advantages of high accuracy and easy operation. In order to avoid the large aperture of Hindle ball when an off-axis convex aspherical surface is under testing
the authors suggest that it be done with off-axis Hindle ball. Hindle ball is used in off-axis configuration
at the same time it can be rotated so that the whole area can be tested. The size of Hindle ball can be reduced
thus the area in the aspherical surface to be tested is increased. The accuracy of the method is also analyzed theoretically.
